Dear R community, Can I please get some advice on the following: I wish
to obtain a list of residuals, padded by NAs for NAs in my source data. I
tried several options of "na.action", but did not succeed...
Example: I would like to get "0,0,0,0,NA,NA":
> a
[1] 1 2 3 4 NA 9
> b
[1] 3 4 5 6 7 NA
> lm(a~b)$residuals
1 2 3 4
0 0 0 0
> lm(a~b,na.action=na.exclude)$residuals
1 2 3 4
0 0 0 0
Thank you and best regards!
Georg.
